EXPANSI BLE-BRACELET LINK.

Specification of Letters Patent.

Patented Nov. 2%, 1914i.

Application filed Novembertl, 1912. Serial No. 729,300

To all whom it may concern Be it known that l, FRED S. ELLIS, a citizen of the United States, and resident of the town of Attleboro, in the county of Bristol and State of Massachusetts, have invented certain new .and useful Improvements in Expansible-Bracelet Links, of which the followingis a specification.

This invention relates to flexible bracelets of the class adapted to be extended or expanded to pass over the hand onto the arm of the wearer, and the object of the invention is to provide such a bracelet with a plurality of interconnecting guide -links and slide links, the guide link being formed of two members having a uniting bridge at one end and interlocking fingers at the opposite end and the slide link being constructed of a strip of metal folded to form an elongated loop and having lugs extending laterally into the recessed portions of the guide members, said links being normally held in contracted position by'a spring, a feature of this invention being that the same may be stamped up out of sheet metal, that each link comprises but two parts outside of the spring and the whole adaptedto be assembled and formed by a simple bending of the stock and without the use of solder.

With these and other objects inview, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims. f

Of the accompanying draw ngs: Flgure 1- is an edge view of an expandible bracelet of my improved construction. Fig. 2- is an enlarged side view illustrating the arrangement of the links and the manner of securing them together. Fig. 3.-'1s an enlarged view of one of the guide links before being folded upon itself showing the con'- necting bridge member and the two interlocking fingers. Fig. 4- shows the guide link as folded with the free ends slightly separated. Fig. 5- is a side elevation showing the two sets of interlocking fingers each as folded about the shank portion of the other. Fig. 6 is an end view showing the interlocking fingers in position to be folded each about the shank portion of the other. Fig. 7'- is an end view illustrating a modincation showing one of the fin ers as! formed on a taper and the other fingeras provided with wings adapted to be folded around the tapered finger for the purpose of locking the free ends of the link together. Fig. 8 is a detail of the slide link as struck from sheet stock. Fig; 9 shows this slide link as constructed of the strip of metal, the same being folded to form an elongated loop with laterally extending lugs at its free ends. Fig. 10- is a sectional end view on line 1'O-l0 of Fig. 11 looking in the direction of the arrow and showing the lateral lugs of the sliding link entering the trough-shaped portion of the guide links. Fig. 11- is a sectional side elevation showing parts of two links connected together. 1 Referring to the drawing, the expandible bracelet is constructed of a plurality of interconnecting guide links 10 and slide links 11, the guide links being preferably struck v up out of sheet stock and comprising two trough-shaped members 12 and 13 connected together by means of a bridge portion-14, the opposite ends of thesemembers being each provided with a finger 15- and 16 respectively. These fingers may be in any desired shape whereby one is adapted to be folded about the other for the purpose 'of securing the free ends of these members together, but I have preferably formed these fingers each with a T-shaped head 17 and 18 forming foldable wings whereby when the members are folded together as illustrated in Figs. 5, 6 and 11, the T-head or wing of each finger is wrapped about the shank or neck portion 19 and 20 respectively. of the opposite finger thereby forming an interlocking construction to securely bind and hold the free ends of these members together.

The slide link 11 is constructed of a strip of metal provided with lugs 21 and 22 respectively extending laterally from its opposite ends. This strip of metal is then folded bringing the opposite or lug ends of the strip together forming an elongated loop as illustrated in Fig; 9. I

In assembling the members the slide link is positioned between the members of the- Elli small coil spring 23 is inserted between the lug end of the slide link and the bridge of the guide link thereby normally holding the two link members in relative contracted position. After similarly mounting up the next link the finger portions of the guide link are passed through the extending end of the slide link and upon wrapping the wing portions of the fingers about each other the two links are firmly secured together. This manner of connecting up the links is duplicated until all of the links of the whole bracelet are connected up which is done by simply bending the stock and entirely without the use of solder.

l. have described the fingers 15 and 16, which are for connecting the free ends of the side members of the guide link, asboth being formed in a Teshape, but I do not wish to be restricted to this particular construction as one of the fingers may be formed in a wedge'or taper shape, as illu trated at at in Fig. 7 and the other linger 25 may be formed in somewhat of a l-shape having wings adapted to be folded about the tapered portion of the linger 2%, whereby when thus folded these ends will be offsetually locked together.

ll claim:

1. in a bracelet, an interconnecting guide link and slide link, said guide link comprising a pair oi. trough-shaped members connested together at one end by an ntegral bridge and folded at said bridge to set opposite and spaced apart from each other the free ends of said members being provided with extending portions folded one about the other to positiyely lock said free ends together said extensions also serving as a cross bar for guiding the slide link, said slide link being slidably mounted between said trough shaped members and a spring for normally retaining said links in contracted position.

2. In a bracelet, an interconnecting guide link and slide link said guide link comprising a pair of trough-shaped members connected together at one end by an integral bridge and folded at said bridge to set opposite and spaced apart -from each other, the free ends of each member being provided with an integral shank having laterally eatending wings, the wings of one being folded about the shank of the other to positively lock said. free ends together, said shanks also serving as a cross bar for guiding the slide link, said slide link being constructed or a strip or metal folded to form an elongated loop and having laterally extending lugs its free ends said lugs I being slidably mounted in said trough shaped members whereby the groove ortion of the trough serves both as a guide 'or said lugs and also to prevent the free ends of the slide link'from separating, and a spring acting on said members for normally retaining said links in relative contracted position in the guide member.

3. In a bracelet, an interconnecting guidelink and slide-link, said guide-link comprising a pair of trough-shaped members connected together at one end by an integral bridge and folded at said bridge to set op- I posite and spaced apart from each other, the free end of one of said members being provided with'a tongue having a lateral projection, the free endot the other of said members being provided with an extension having a laterally extending ear wrapped around said tongue, said slide-link being slidably mounted between said troughshaped members and a spring for normally retaining said links in contracted position.

4:. in a bracelet, an interconnecting guide link and slide-link said guide-link comprising a pair oi trough-shaped members con nected at one end by an integral bridge and folded at said bridge to set opposite and spaced apart from each other the free end of one of said members being provided with a tongue having a lateral projection, the free end oil the other of said members being provided with an extension having two laterally extending ears wrapped around said tongue, said slidedink being slidably mounted between said troughshaped members and a spring for normally retaining said links in contract-ed position.

5. in a bracelehan interconnecting guidelink and slide-link said guidedink comprising a pair of trough'shaped members connected together at one end by integral bridge and folded at said bridge to set opposits and spaced apart from each other. the free end of one of said members being pro vided with a fan-shaped tongue, the free end oi the other of said members being provided, with an extension having two laterally eirtending ears wrapped around said tan shaped tongue, said slide-link being slidably mounted between said troughshaped members and a spring for normally retaining said links in contracted position.
